President Donald Trump is hosting a UFC event on the White House grounds, marking America's 250th anniversary and his 80th birthday. The event has sparked controversy, with critics and some Republicans questioning the timing and costs, especially in light of the war with Iran. The White House has put in place detailed plans for the event's demobilization, including the removal of the 'Claw' structure and turf remediation. The UFC is footing the bill for production costs, but taxpayers are also contributing. The event has grown beyond the White House and National Mall, with complex security measures and road closures. The main card takes place at 8 p.m. ET, and there are contingency plans in place for weather disruptions. The event has also sparked a collaboration between the Trump family and the UFC, with the sale of 'Trump Coins' and the transformation of the Indian Treaty Room into a locker room for fighters. The event has generated enthusiasm among MAGA allies, but it has also drawn rebukes from Trump critics. The UFC has retained control of most tickets, with Trump personally selecting staff members for the remaining spots. The event is expected to reenergize young men who supported Trump's 2024 victory but have since drifted away from the GOP. The site of the event is included in a severe thunderstorm watch, and the National Weather Service will have a meteorologist on-site to monitor conditions.
